Muscle relaxers are a group of drugs that reduce tension and spasm in muscles and have an overall sedative effect on the body. Muscle-relaxing drugs are designed to depress the central nervous system. There are two main types of muscle relaxers: spasmolytics and neuromuscular blockers.
The muscle-relaxing effects of these medicines are most likely the result of their ability to depress the central nervous system. Muscle relaxants can be helpful when severe muscle spasms follow the start of low back pain. Muscle relaxants are not recommended for use by pregnant women, older adults, or people who have depression or a history of drug or alcohol addiction.
